10.0 mL 0.5 M sulfuric acid neutralizes ________ mL 0.5 M magnesium hydroxide.

Question

Quizplus · Accepted Answer

The neutralization reaction between sulfuric acid and magnesium hydroxide is as follows:
H2SO4 + Mg(OH)2 → MgSO4 + 2H2O
This is a 1:1 molar ratio reaction, meaning that 1 mole of H2SO4 reacts with 1 mole of Mg(OH)2. 
Since the concentration of both the acid and base is the same (0.5 M), it would take the same volume of each to completely neutralize the other. 
Therefore, 10.0 mL of 0.5 M sulfuric acid would neutralize 10.0 mL of 0.5 M magnesium hydroxide. 
The correct answer is B, which represents 10 mL.
